Easy way to translate avatars to English. Click on your avatar (# 1) and then look over to the Inspector (# 2). Scroll down to the Expressions Menu (# 3) while having your Project folder visible click on the Expressions menu (# 3). You will see the menu flash in your projects folder (4).
Once you click on (# 4) it will change in your inspector to the menu the only thing you would need to change is (# 5) put whatever text that is there into google translate. It is totally optional to change (# 6) but not necessary at all. Just repeat this for everything in the menu. Some things will not translate great but can always be changed later. If you are not sure you can always put ??? or something and then upload it and check it in game.
Hope this helps a bit
